An injection site injury may be misdiagnosed as a pressure ulcer, and vice versa.


The buttocks is the site where an injection site injury and pressure ulcer can be confused.


A site of injection injury is more likely to become a pressure ulcer since the tissue is already injured. The risk may be increased for:

(1) panniculitis

(2) abscess or cellulitis

(3) vasoconstricting drug with ischemia


Barriers to diagnosis:

(1) patient transfer

(2) undocumented injection

(3) patient unable to give a history (coma, sedation, etc)

(4) injection of a drug of abuse
